Abstract

Obstructive jaundice of the bile duct resulting from tumor-producing copious, thick mucin, causing ductal obstruction and dilatation, has been reported very rarely. Also, the benign bile duct neoplasm is extremely rare. We report a case of a mucin-secreting villous adenoma of common hepatic duct causing obstructive jaundice and cholangitis. The patient was a 72-year-old male and had a 3 yeared history of common hepatic mass unchanged remarkably in size. The abdominal ultrasonogram and computed tomography revealed well circumscribed, more than 2cm sized mass on the CHD and ductal dilatation. We were able to get an interesting cholangioram showing irregular, nodular, ill defined filling defect in the extrahepatic bile duct, different from US and CT findings, And it was just caused by thick, copious mucin from the tumar. This case was confirmed as mucin-secreting villous adenoma after surgery.
